SAMUEL H. HAAS, OF PHILADELPHIA, PENNSYLVANIA.

SHAFT-TUG.

SPECIFICATION forming part of Letters Patent No.471,818,`dated March 29,1892.

Application filed J'nly 15, 1891. Serial No. 399,582. (No model.)

To all whom t may concern,.-

Be it known that I, SAMUEL H. Hans, a citi-- zen of the United States,and a resident of Philadelphia, Pennsylvania, have invented certainImprovements in Shaft-Tilgs, of which the following is a specification.

One object of my invention is to so construct a shaft-tug for harness asto prevent the chaiing or abrading of the shaft by the tug, a furtherobject being to provide for the attachment of the tugto the saddle-strapwithout the employment of. the usual buckle. These objects I attain inthe manner hereinafter set forth, reference being'had to theaccompanying drawings, in which- Figure 1 is a perspective view of theshafttug constructed in accordance with my invention, and Fig. 2 is alongitudinal sectional view of the same.

The tug consists, essentially, of a shaft-supporting hook A and aspring-tongue B, closing the mouth of the hook, this tongue in thepresent instance being hung to a transverse pin a and acted on by'aspring b, which tends to close it, but permits of its movement to theposition shown by dotted lines in Fig. 2, in order to provide for theintroduction or withdrawal of the shaft, which is shown by dotted linesin Fig. 2. The hook A is open at the rear, but has opposite cheek-piecesd, connected by transverse pins f and g, the pin f receiving the loopedupper end of the bellyband D and the pin g serving as a bearing for thesaddle-strap F, which has a series of openings t', to any one of whichmay be adapted'a projecting pin m on a cross-bar m ofA the hook, asshown in Fig. 2. The upper end of the spring-tongue B has an opening forthe reception of the projecting pin m, and into this opening projects adepending finger ot, which serves to bear upon the saddle-strap andprevent the same from slipping outwardly on the said pin m to such anextent as to be released therefrom, that portion of the saddle-strapwhich is below the pin g being retained in position by being tuckedbetween the band D and the bottom of the hook A, as shown in Fig. 2, sothat the traces cannot catch upon said lower end of the strap. Thespringtongue B of the tug has on the back adjacent to the lower end orpoint a rearwardly-projecting toe p, which by contact with the top ofthe shaft serves to prevent the rise of the latter in the tug, and thusprecludes any jamming of the shaft in the tapering space formed by thespring-finger and the back of the hook, chating or abrasion of the topand upper corners of the shaft being thus effectually prevented, whilethe strap F projects forward' beyond the cheek-pieces d, and thusprevents contact of the inner side of the shaft with the latter.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. The combination of the hook having a projecting pinat the upper end with the spring-tongue closing the mouth of the hookand having an opening` for the reception of said pin and a dependingfinger projecting into said opening toward the pin, substantially asspecified. l

2. The combination of the hook having cpposite cheek-pieces atthe rear,a springtongue closing the mouth of the hook, a pin projecting from theupper portion of the hook and adapted to an opening in the saddle-strapand to an opening in the tongue, and a transverse pin forming a bearingfor said saddlestrap below the retaining-pin', substantially asspecified.

3. The hook having a spring-tongue7 an open back with oppositecheek-pieces, a projecting pin, and a bar for receiving the bellyband,said bar occupying such relation to the" inner edges of the cheek-piecesthat when the saddle-strap is passed downward between the belly-band andthe bottom of the hook said strap will project forward beyond thecheekpieces of the latter, substantially as specified. In testimonywhereof I have signed my name to this specification inthe presence oftwo subscribing witnesses.
